Most will agree that the top three PSU manufacturers are
1. PC Power and Cooling
In that order also. I have used all three and can testify to their performance, although you guys are right, generic PSUs will work fine. They wouldn't sell if they didn't. When it comes to overclocking though, things change. Volt mods draw more power and at higher speeds when things become less stable a lower-noise/ripple PSU line can be the difference between a night of burning in with Prime95 and a lockup after 5 minutes. For average users a cheapo PSU will work well but for an overclocker I recommend something more. If you want stability at high overclocks then you just can't entertain the idea of a bargain PSU.
